How to ask more than one multiple choice question?

October 13, 2022

I would like to write a simple bash script for training multiple choice tests. Ask one question; give four choices (a, b, c, d); if user enters input, show if it is wrong or right and continue with the next question.

Here is my code so far:

#!/usr/bin/bash

echo Question1="How much is 2+2?"
echo a="1"
echo b="2"
echo c="3"
echo d="4"
read Question1

if [ "$Question1" = "d" ];
then
    echo "this is correct"
else
    echo "this is NOT correct"
fi

All samples about the read command example I found so far on youtube etc. stop after one question. How can I ask multiple questions? Entering another question does not work and bash shows a syntax error:

#!/usr/bin/bash

echo Question1="How much is 2+2?"
echo a="1"
echo b="2"
echo c="3"
echo d="4"
read Question1

if [ "$Question1" = "d" ];
then
    echo "this is correct"
else
    echo "this is NOT correct"

echo Question2="How much is 2+1?"
echo a="1"
echo b="2"
echo c="3"
echo d="4"
read Question2

if [ "$Question2" = "c" ];
then
    echo "this is correct"
else
    echo "this is NOT correct"
fi
